There is never a “one size fits all” when it comes to threading inserts. Things like the grade of the steel pipe, programming, RPM and depth of cut all come into play when figuring out which carbide substrate and coating combination will work best for our customers.
Knowing what the inserts will be cutting helps us determine which carbide substrate and coating will work best for that application.
The carbide substrate is the material of the bare cutting insert prior to the insert being coated. Carbide is primarily composed of a tungston-carbon combination called WC which makes up 85-95% of the carbide. The other 5-15% is the Cobalt added to the substrate which determines the carbide’s overall hardness. At Lone Star, we have different substrate grades and coatings to offer our customers based on their tooling needs.

The coating is applied on top of the bare carbide to add extra durability and increase tool life. Coatings are chosen based on type of steel being used as well as the operator’s preference of machining speeds. These are all things that can be discussed when designing a custom insert for our customer.
The photo on the left shows inserts coated in different coating grades. The different colors reflect the varying chemical composition of each coating. We always work with our customers until we find the perfect substrate and coating combination that works best for them.

Above is a photo of inserts from one of our customer’s premium threads. All of these inserts are exactly the same except they have different coatings based on our customer’s needs. The different colors reflect the varying chemical composition each coating. We always work with our customers until we find the perfect substrate and coating combination that works best for them.
